I just tested that.
Here is what I did with my actual FA :
E82_#1114&GCSW%0A22*UC71$1CA$1CB$1CD$205$249$2MR$2 PA$321$337$441$468$473$481$4MG$502$522$534$540$548 $663$6FL$6NN$704$760$775$7XA$845$854$863$884-A080
(you can see $663 / $6FL / $6NN)

I injected a blank FSW PSW in the 2RAD module.
We can see 'Bluetooth' and 'RAD_Bluetooth' are disabled... I don't know why because $6NN is written in the FA...

Then I manually modified this settings to 'aktiv' and coded it to the 2RAD module.

Same result, still no Bluetooth in the menu (ignition started)...
This is really weird.

I added the FSW PSW result (after injected a blank file) and the one I modified to make BT works.
